Answer:

Step-by-step explanation:
Given 2 similar figures with ratio of sides = a : b, then
ratio of areas = a² : b²
Here ratio of sides = 52 : 68 = 13 : 17 ← in simplest form, thus
ratio of areas = 13² : 17² = 169 : 289 = 
Answer:
Yes
Step-by-step explanation:
13(10) + 15(1) 
130+15 
145
← Yes it is
-8k - 8(-8k + 6) = -8k + 64k - 48 = 56k - 48
The answer is 78.46 hope this helps
